Cabbage caterpillars can attack all stages of plant growth in the vegetative and generative phases. In the concept of integrated pest control, the use of chemical insecticides is the last alternative, so an environmentally friendly control technology is needed. Swampland has the potential of plants that can be extracted as active ingredients for pest control. The results of the literature study showed that there were several types of potential wetland plants that contained the active ingredient of hydrocarbon derivative compounds which were effective in controlling Plutella, but of the 13 types of plants, a study was conducted on their effectiveness in controlling Pluttela xylostella larvae is very necessary. The purpose of this study was to determine the effectiveness of various types of wetland plants as effective botanical insecticides in controlling Pluttela xylostella on a laboratory scale. The results showed that there were 13 types of swamp plants that could be effective botanical insecticides in controlling Pluttela xylostella. The mortality of Pluttela xylostella larvae at 48 hours of observation was high in the treatment of plant extracts of Piper sarmentosum, Tithonia diversifolia, and Ziziphus spina-christi with a percentage of 68%. Therefore, it is necessary to conserve these wild plants so that these plants do not become extinct.

An efficient cheap source of activated carbon as solid phases for extraction and removal of Congo Red from aqueous solutions

The present study reported the preparation of solid phases from various available and cheap natural sources represented by activated carbon to remove the polluting dye Congo Red (CR). Activated carbon derived from the leaves of the Consocarpus plant (C/AC) and Ziziphus Spina-Christi plant (Z/AC) and Myrtus plant (M/AC) by chemical activation. The solid phases were diagnosed and examined using FTIR, FESE, and XRD. The results of the study indicated that the best amount for the solid phase was 0.25 g for the three solid phases used against dye, the optimal concentration of the CR was 100 mg L-1, and the optimum acidity function was equal to 5 with a volume of 25 mL, as the optimization experiments indicated that the best flow rate of the eluting solution was equal to 0.5 ml min-1. The elution processes were carried out using several solvents different in polarity and it was found that 8 mL of DMSO achieved the best percentage of recovery (%R). Also, the adsorption capacity based on the optimal conditions that were obtained by applying Langmuir and Freundlich isotherm models, and qmax, according to the Langmuir model, was (21.74, 23.53, 22.17) mg g-1 for (Z/AC), (C/AC), and (M/AC) adsorbents, respectively.

Antioxidant, Protoscolicidal, Hemocompatibility, and Antibacterial Activity of Nickel Oxide Nanoparticles Synthesized by Ziziphus spina-christi

Over the past several years, the greener fabrication of metal oxide nanoparticles has attracted significant attention due to their simplicity, eco-friendliness, availability, and nontoxicity. This paper focused on the fabrication of nickel oxide nanoparticles (NiO-NPs) using the leaf extract of Ziziphus spina-christi L. and evaluating its potential biological activities. The characterization of synthesized NiO-NPs was confirmed using ultraviolet–visible spectroscopy, field emission-scanning electron microscope, energy-dispersive X-ray spectroscopy, and X-ray diffraction. Furthermore, protoscolicidal, antibacterial, and antioxidant activities and hemocompatibility of NiO-NPs were investigated. The findings revealed that the NiO-NPs were crystalline on nanoscale between 50- and 90-nm particle sizes. The NiO-NPs showed high scolicidal activity against Echinococcus granulosus. The viability of the treated protoscoleces exponentially decreased with an increase in the concentration of NiO-NPs. The NiO-NPs exhibited effective antibacterial activity against Escherichia coli and Staphylococcus aureus. NiO-NPs also possess a H2O2 scavenging activity in a dose-dependent manner. This study revealed that the Z. spina-christi L. leaf extract is an effective reducing and capping agent for the production of NiO-NPs; it showed critical biological properties. Moreover, NiO-NPs have a potent antioxidant activity and low toxicity on the erythrocytes and appear hemocompatible.

Use of Saponinosomes from Ziziphus spina-christi as Anticancer Drug Carriers.

Saponins are plant glycosides with different structures and biological activities, such as anticancer effects. Ziziphus spina-christi is a plant rich in saponin, and this compound is used to treat malignant melanoma in the present study. Nanophytosomes can be used as an advantageous nanodrug delivery system for plant extracts. The aim of this work is to use the saponin-rich fraction (SRF) from Z. spina-christi and prepare SRF-loaded nanophytosomes (saponinosomes) and observe the in vitro and in vivo effects of these carriers. First, the SRF was obtained from Z. spina-christi by a solvent–solvent fractionation method. Then, Fourier transform infrared (FTIR) analyses were performed to confirm the presence of saponins in the extracted material. Subsequently, the saponinosomes were prepared by the solvent injection method (ether injection method) using a 1:1:1 ratio of lecithin/cholesterol/SRF in the mixture. Characterization of the prepared saponinosomes was performed by FTIR, dynamic light scattering (DLS), field-emission scanning electron microscopy (FE-SEM), and atomic force microscopy (AFM) analyses. In addition, a UV–vis spectrophotometer was used to determine the entrapment efficiency (EE) and in vitro release of the SRF. Finally, cell cytotoxicity of the different formulations was evaluated using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay on both mouse melanoma cells (B16F10) and fibroblasts (L929). Using DLS, AFM, and FE-SEM analyses, the particle size was determined to be 58 ± 6 nm with a zeta potential of −32 ± 2 mV. The calculated EE was 85 ± 3%. The results of the in vitro release profile showed that 68.2% of the SRF was released from the saponinosome after 48 h. The results of the MTT assay showed that the SRF and saponinosomes have high toxicity on B16F10 melanoma cells, but saponinosomes showed a significant decrease in cytotoxicity on L929 fibroblast cells compared with that of the SRF. Our results indicate that the SRF from Z. spina-christi has anticancer activity, and the saponinosomes prepared in this work can control tumor growth, improve therapeutic efficacy, and reduce the side effects of saponins.

Study the mechanical properties of epoxy resin reinforcement by ziziphus spina-christi powder

Ziziphus Spina-Christi bark and other natural debris may be found in abundance in the nearby area. The mechanical qualities of all of these waste natural resources are outstanding, and they may be utilized more professionally to create composite materials for a variety of applications. Epoxy resin modified with organic natural particles such as Ziziphus Spina-Christi bark powder has been used as reinforcements in polymer matrixes instead of non-degradable synthetic reinforcement such as glass, carbon, or aramid. The tensile, impact and flexural characteristics of the Ziziphus Spina-Christi bark particles enhanced epoxy resin are examined in this publication. This paper studies the effects of weight fraction (3, 5, 7 & 9%) on the characterization of composite materials. The results show that the mechanical characterization of epoxy improved when added 7% from the particles of Christi. Where the hardness increased up to 77 (Mpa). Also, the impact strength reached 8.7 (KJ/m2 ) with a 7 wt% filler added, and the tensile strength increased from 18 (MPa) to 45 (MPa). The flexural strength of pure epoxy is 160 (MPa), and it increases linearly with the addition of Ziziphus Spina-Christi bark to 173 (MPa).

Biogenic synthesis of reduced graphene oxide from Ziziphus spina-christi (Christ’s thorn jujube) extracts for catalytic, antimicrobial, and antioxidant potentialities

In the current work, various concentrations of the aqueous extract of Ziziphus spina-christi were employed for the phytoreduction of graphene oxide (GO). The green synthesized reduced graphene oxide (rGO) was characterized through UV-Vis spectrometry, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy, and energy-dispersive X-ray spectroscopy (SEM-EDX). Gas chromatography-mass spectrometry (GC-MS) denoted the presence of numerous phytoconstituents including ketones, terpenoids, fatty acids, esters, and flavonoids, which acted as reducing and capping agents. The obtained results indicated the increase in rGO yield and shape with increasing the extract concentration. The optimized rGO was instantaneously ~100% removed methylene blue (MB) from the water at 5 mg L−1. However, the removal efficiency was slightly declined to reach 73.55 and 65.1% at 10 and 15 mg L−1, respectively. A powerful antibacterial activity for rGO particularly against gram-negative bacteria with a high concentration of 2 × 108 CFU mL−1 was confirmed. Furthermore, rGO demonstrated promising and comparable antioxidant efficiency with vitamin C against DPPH free radical scavenging. While vitamin C recorded 13.45 and 48.4%, the optimized rGO attained 13.30 and 45.20% at 12 and 50 μg mL−1, respectively.

Adsorptive separation of dissolved cadmium from aqueous solution using (Ziziphus Spina-Christi) leaves as an adsorbent

Sidr (Ziziphus spina-christi) leaves powder was tested extensively to find out its ability as cadmium ions adsorbent. Parametric studies were carried out in a batch system and the results showed that removal efficiency increased to 98% when using an adsorbent dosage of 2 g L−1 and stayed high when the initial concentration was less than 100 ppm. Adsorption temperature might be maintained at less than 40 °C and the recommended pH was found to be in the range of 4.5–5.5. The main and effective functional groups detected on the surface of the adsorbent by using Fourier transform infrared spectroscopy were carboxylic acid, alcohol, nitro and alkyl halides groups. Isotherm equilibrium results depicted that the sequence of model fitness to experimental data (based on R2) was: Langmuir > Freundlich > Harkin-Jura > Jovanovic > Temkin > Dubinin –Radushkevich. Linear and non-linear equilibrium, and kinetics models were experienced. Maximum metal uptake, 95.2 mg/g was evaluated using a linearized form of the Langmuir model having higher R2 than a non-linear model. Kinetic and thermodynamics predictions revealed that mass transfer across the aqueous boundary layer, intra-particle diffusion, and exothermic pseudo-first-order reaction on the adsorbent surface were the main mechanisms of Cd(II) adsorption on the present adsorbent. Ten adsorption-desorption cycles were performed to evaluate the adsorbent reusability. In conclusion, the novelty of this work represents the successively chosen of sidr leaves as a new, abundant, low-cost, and favorable adsorbent for the removal of cadmium cations from aqueous solutions.

Effects of Fermented Camel Milk Supplemented with Sidr Fruit (Ziziphus spina-christi L.) Pulp on Hyperglycemia in Streptozotocin-Induced Diabetic Rats

Diabetes is one of the most common chronic metabolic diseases, and its occurrence rate has increased in recent decades. Sidr (Ziziphus spina-christi L.) is a traditional herbaceous medicinal plant. In addition to its good flavor, sidr has antidiabetic, anti-inflammatory, sedative, analgesic, and hypoglycemic activities. Camel milk has a high nutritional and health value, but its salty taste remains the main drawback in relation to its organoleptic properties. The production of flavored or fortified camel milk products to mask the salty taste can be very beneficial. This study aimed to investigate the effects of sidr fruit pulp (SFP) on the functional and nutritional properties of fermented camel milk. SFP was added to camel milk at rates of 5%, 10%, and 15%, followed by the selection of the best-fermented product in terms of functional and nutritional properties (camel milk supplemented with 15% SFP), and an evaluation of its hypoglycemic activity in streptozotocin (STZ)-induced diabetic rats. Thirty-two male adult albino rats (weighing 150–185 g) were divided into four groups: Group 1, nontreated nondiabetic rats (negative control); Group 2, diabetic rats given STZ (60 mg/kg body weight; positive control); Group 3, diabetic rats fed a basal diet with fermented camel milk (10 g/day); and Group 4, diabetic rats fed a basal diet with fermented camel milk supplemented with 15% SFP (10 g/day). The results revealed that supplementation of camel milk with SFP increased its total solids, protein, ash, fiber, viscosity, phenolic content, and antioxidant activity, which was proportional to the supplementation ratio. Fermented camel milk supplemented with 15% SFP had the highest scores for sensory properties compared to other treatments. Fermented camel milk supplemented with 15% SFP showed significantly decreased (p < 0.05) blood glucose, malondialdehyde, low-density lipoprotein-cholesterol, cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, creatinine, and urea, and a significantly increased (p < 0.05) high-density lipoprotein-cholesterol, total protein content, and albumin compared to diabetic rats. The administration of fermented camel milk supplemented with 15% SFP in diabetic rats restored a series of histopathological changes alonsgside an improvement in various enzyme and liver function tests compared to the untreated group, indicating that fermented camel milk supplemented with 15% SFP might play a preventive role in such patients.

Evaluation of soil physico-chemical properties as affected by canopies of scattered agroforestry trees on croplands

Agroforestry tree species play an important role in improving soil fertility. Though studies have confirmed that different species show different potentials to improve soil fertility, it is difficult to compare them as the studies were conducted in different areas. The potential for different tree species to improve soil fertility on croplands in northern Ethiopia is not known. The objectives of this paper are to determine the effects of presence or absence of agroforestry tree species on soil physico-chemical properties and the effect of distance from the tree trunk on the same soil physico-chemical properties. Sixty composite and undisturbed soil samples from beneath canopies and outside canopies and 90 composite and undisturbed soil samples from three different distances from tree trunks were collected. The results revealed that soil bulk density, soil moisture, soil organic carbon (SOC), total nitrogen (TN), available phosphorus (Av.P), exchangeable potassium (Exch.K) and soil organic carbon stock (SOCS) were significantly (p < 0.05) different between soils beneath canopies and outside canopies as well as at different distances from the tree trunk. Soils around these agroforestry tree species have increased SOC, TN, Av.P, Exch.K and SOCS by 11.9 to 91.5%, 22.2 to 125.0%, 31 to 71%, 32 to 151.6% and 15.2 to 90.9%, respectively, compared to soils outside tree canopies. Faidherbia albida (Delile) A.Chev. has the highest potential for soil fertility compared to Balanites aegyptiaca (L.) Delile, Cordia africana Lam., Ziziphus spina-christi (L.) Desf., Acacia sieberiana DC and Croton macrostachyus Hochst. ex Delile. This study could provide useful information for soil fertility management and farmers’ decision-making when selecting tree species. The findings of this study imply that scattered trees on croplands significantly improve soil fertility and reduce the need for external fertiliser inputs.
